A Zombie Cookie is a type of tracking technology that uses blockchain to re-establish user tracking after they’ve deleted their cookies. Regular cookies store information on a user’s device, which can be removed when a user clears their browser data. However, Zombie Cookies are designed to regenerate after deletion.These cookies rely on data stored in other locations, such as Adobe Flash storage or specific identifiers tied to the user’s device. When a user thinks they’ve removed tracking, the Zombie Cookie can reappear, continuing to collect user data without their consent.In the context of privacy, Zombie Cookies raise significant concerns. They can undermine users’ efforts to protect their personal information online. As regulations like GDPR aim to enhance privacy protections, technologies like Zombie Cookies become increasingly scrutinized.This practice highlights the ongoing tension between advertising and user privacy, prompting discussions about ethical data collection methods and the need for transparency in online tracking.
